TECHNICAL FIELD

The present invention relates to the field of network communication technologies, and more particularly, to a network data transmission method, device and system.

RELATED ART

At present, in a network transmission process, after a client terminal and a server establish a connection of transport layer, the client terminal can initiate a network request to the server; if the server receives the network request transmitted by the client terminal, the server would feed back to the client terminal information corresponding to the network request.

Each network request transmitted by the client terminal to the server may generally contain some fixed information, for example, User Agent, Accept and other fields. In different network requests, sometimes, the fixed information is the same contents. As the network request transmitted by the client terminal to the server contains a significant amount of repeated contents, this not only wastes the data traffic of the client terminal but also extends the time to transmit the network request to the server by the client terminal, thus reducing the speed at which the client terminal accesses the network.

Therefore, how to increase the speed at which the client terminal accesses the network becomes a technical problem to be urgently solved at present.

DETAILED DESCRIPTION

The technical solutions in the embodiments of the present invention will be clearly and fully described below with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the embodiments to be described are only some rather than all of the embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without carrying out creative activities should fall within the protection scope of the present invention.

In the embodiments of the present invention, a network data transmission method, device and system are provided; as there are many various specific implementations of the network data transmission method, device and system, detailed description is given below through specific embodiments:

Embodiment 1

Referring to FIG. 1, FIG. 1 illustrates one network data transmission method. The method is applied to a client terminal. The method provided in this embodiment can avoid wasting data traffic of the client terminal and reduce the time to transmit the network request to the server by the client terminal, thus improving the speed at which the client terminal accesses the network. The method includes:

Step S101. A network request is acquired.

The network request refers to a network request between a client terminal and a server, for example, a Hypertext transfer protocol (HTTP) request header. A person having ordinary skill in the art should appreciate that the network request may also be other requests. As each network request contains a great number of repeated data, the client terminal is transmitting to the server a significant amount of repeated data all the time.

An example of a network request is displayed below. In order to save space, only some data of the network request is displayed, for example, a network request transmitted to the server by the client terminal for the first time is as follows:

“Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8

Host: baidu.com”

A network request transmitted to the server by the client terminal for the second time is as follows:

“Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8

Host: 163.com”

It can be understood through the contents of the two network requests that the contents of the Accept field are the same, while the contents of the Host field are different. In an actual scenario, a great number of repeated fields may exist, and thus a problem to be solved in the present invention is how the meaning of the original network request can be expressed without transmitting the repeated fields, thereby reducing the contents of the network request.

Step S102. The network request is compared with a network request template pre-stored on the client terminal to obtain discrepant data and identical data.

The client terminal may store multiple network requests that have been transmitted before, and take the pre-stored network requests as network request templates. After the client terminal newly generates a network request, the network request is compared with a pre-stored network request template, so as to obtain discrepant data and identical data. The discrepant data refers to a part of the network request which is added relative to the network request template, and the identical data refers to a part of the network request which is identical to the network request template.

Step S103. Position information of the discrepant data and the identical data in the network request template is determined.

After the discrepant data and the identical data are obtained, position information of the discrepant data and the identical data in the network request template is determined. The functions of the position information are as follows: it is possible to find the identical data in the network request template by using the position information. It is also possible to determine by using the position information what position the discrepant data should be placed in the network request template, and thus the network request can be restored by using the position information, the discrepant data and the network request template.

During step S102 and step S103, it is feasible to use one algorithm for implementation. For example, discrepancy operation is performed on the network request and the network request template through a reversible binary diff (command comparison text file) algorithm, and the discrepant data and the position information can be obtained finally through the above algorithm. A person having ordinary skill in the art should appreciate that it is also feasible to use other methods for implementation. For example, an open source xdelta algorithm, a google's vcdecoder algorithm, an open source diffutils algorithm and so on, all of which can achieve discrepancy operation on the network request and the network request template. Finally, the discrepant data and the position information calculated are taken as actually transmitted parts, and as the discrepant data does not have the same part between the network request and the network request template, the size of the discrepant data may be far less than that of the original network request.

Step S104. Identification information of the network request template, the discrepant data and the position information are transmitted to a server, where the identification information will be used to search for, by the server, the network request template pre-stored on the server and corresponding to the identification information, and the network request template, the discrepant data and the position information will be used to restore, by the server, the network request.

The identification information of the network request template, the discrepant data and the position information are transmitted to the server, in order that the server restores the network request by using the network request template, the discrepant data and the position information. The identification information of the network request template refers to a unique identifier of the network request template, which may be represented with several characters. For example, identification information of a certain network request template is specifically BZ1001. A person having ordinary skill in the art should appreciate that there are many coding manners of the identification information of the network request template, which are not repeated herein one by one.

In addition, the identification information may be obtained by using a preset algorithm to calculate data in the network request template. For example, the data in the network request template is calculated by using a Message-Digest Algorithm 5 (MD5) algorithm or a hashkey algorithm, to obtain a unique 8-byte id value, and the id value is used to represent a network request template. In order to authenticate whether the data transmitted to the server by the client terminal is correct or not, it is feasible to calculate the data in the network request by using the MD5 algorithm or the hashkey algorithm to obtain an authentication code and transmit to the server the authentication code; after the server receives the authentication code, the server may calculate data of the restored network request by using the MD5 algorithm or the hashkey algorithm to obtain an information code. Then the server compares whether the authentication code and the information code are the same or not. If they are the same, it indicates that the transmitted data is flawless, and if they are not the same, it indicates that the transmitted data is flawed.

In the embodiment shown in FIG. 1, data transmitted to a server by a client terminal includes identification information of a network request template, discrepant data and position information, and as the data transmitted to the server by the client terminal does not include identical data of a network request and the network request template, a significant amount of repeated contents are reduced, thus reducing transmission of network data; moreover, after receiving the data transmitted by the client terminal, the server can restore the network request by using the network request template, the discrepant data and the position information, thus ensuring correctness of the transmission of network data. Therefore, the solution according to the present invention reduces the time to transmit a network request to the server by the client terminal while ensuring proper transmission of network data, thus improving the speed at which the client terminal accesses the network.

The solution according to the embodiment of the present invention is described below through a specific example:

It is assumed that the network request is as follows:

“Accept:text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8

Host: baidu.com”

the network request template is as follows:

“Accept:text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8

Host: 163.com”

In the following, discrepancy operation is performed on the network request and the network request template through a reversible binary diff algorithm. At first, the network request is compared with a pre-stored network request template to obtain discrepant data and identical data, and then position information of the discrepant data and the identical data in the network request template is determined, so as to obtain data as follows:

(0, 70, 0)

(0, 5, b) aidu (8, 4, 0)

Elements in the parentheses refer to position information of the identical data in the network request and the network request template, and contents between the parentheses refer to discrepant data, because positions between the parentheses refer to position information of the discrepant data. The specific meaning of the data in the parentheses is (starting position, read length, end symbol). For example, the first “0” in (0, 70, 0) represents a starting position, that is, start from the first character “A” on the first line of the network request template; “70” in (0, 70, 0) represents a read length, that is, starting from the first character “A” of the network request template, 70 characters are read until the first line of the network request template ends; the second “0” in (0, 70, 0) represents an end symbol, and “0” is used to represent null as the first line has ended.

In (0, 5, b), the first “0” refers to that the starting position of the second line of the network request template is “H”. In the process of comparing the network request with the network request template, it is found that 5 successive characters on the second line are the same. They are different from the sixth character, and the sixth character of the network request is “b”. Therefore, the first six characters of the network request are represented with (0, 5, b). When the seventh character on the second line of the network request is compared with the seventh character on the second line of the network request template, a difference is found, and the seventh character on the second line of the network request is compared with characters after the seventh character on the second line of the network request template, to determine that there is no data identical therewith, thus defining the seventh character “a” on the second line of the network request as discrepant data. It can be known from the method that the discrepant data further includes “idu”. After the discrepant data has been determined, it is found that the eleventh character to the fourteenth character “.com” on the second line of the network request are identical to the ninth character to the twelfth character “.com” on the second line of the network request template, and thus (8, 4, 0) is obtained.

Therefore, it is feasible to perform discrepancy operation on the network request and the network request template through a reversible binary diff algorithm, so as to obtain discrepant data and position information; moreover, the diff algorithm is reversible, network data can also be reversely obtained by using the network request template, the discrepant data and the position information, so as to be suitable for the problem to be solved in the embodiment of the present invention, that is, the same part in the network request and the network request template is deleted, and only the identification information of the network request template, the discrepant data and the position information are transmitted, to reduce the transmission amount of the data of the transmitted network request.

Embodiment 2

Referring to FIG. 2, FIG. 2 illustrates another network data transmission method. The method is applied to a client terminal. The method provided in this embodiment can avoid wasting the data traffic of the client terminal and reduce the time to transmit the network request to the server by the client terminal, thus improving the speed at which the client terminal accesses the network. The method includes:

Step S201. A network request is acquired.

The network request refers to a network request between a client terminal and a server, for example, an HTTP request header. A person having ordinary skill in the art should appreciate that the network request may also be other requests. As each network request contains a great number of repeated data, the client terminal is transmitting to the server a significant amount of repeated data all the time.

Step S202. Whether or not the network request is identical to the network request template is judged, if yes, step S203 is performed, and otherwise, step S204 is performed.

It is likely that a network request newly generated by the client terminal is identical to a pre-stored network request template. if they are identical, the client terminal only needs to transmit to the server identification information of the network request template, thus reducing the data amount transmitted to the server by the client terminal and reducing the time for transmitting the network request to the server by the client terminal.

Step S203. Identification information of the network request template is transmitted to the server.

Step S204. The network request is compared with a network request template pre-stored on a client terminal to obtain discrepant data and identical data.

The client terminal may store multiple network requests that have been transmitted before, and take the pre-stored network requests as a network request template. After the client terminal newly generates a network request, the network request is compared with a pre-stored network request template, so as to obtain discrepant data and identical data. The discrepant data refers to a part of the network request which is added relative to the network request template, and the identical data refers to a part of the network request which is identical to the network request template.

Step S205. Position information of the discrepant data and the identical data in the network request template is determined.

After the discrepant data and the identical data are obtained, position information of the discrepant data and the identical data in the network request template is determined. The functions of the position information are as follows: it is possible to find the identical data in the network request template by using the position information, it is also possible to determine by using the position information what position the discrepant data should be placed in the network request template, and thus the network request can be restored by using the position information, the discrepant data and the network request template.

During step S204 and step S205, it is feasible to use one algorithm for implementation. For example, discrepancy operation is performed on the network request and the network request template through a reversible binary diff algorithm, and the discrepant data and the position information can be obtained finally through the algorithm. A person having ordinary skill in the art should appreciate that it is also feasible to use other methods for implementation. For example, an open source xdelta algorithm, a google's vcdecoder algorithm, an open source diffutils algorithm and so on, all of which can achieve discrepancy operation on the network request and the network request template. Finally, the calculated discrepant data and the position information are taken as actually transmitted parts. Because the discrepant data does not have the identical part between the network request and the network request template, the size of the discrepant data may be far less than that of the original network request.

Step S206. The identification information of the network request template, the discrepant data and the position information are transmitted to a server, where the identification information will be used to search for, by the server, the network request template pre-stored on the server and corresponding to the identification information, and the network request template, the discrepant data and the position information will be used to restore, by the server, the network request.

The identification information of the network request template, the discrepant data and the position information are transmitted to the server, in order that the server restores the network request by using the network request template, the discrepant data and the position information. The identification information of the network request template refers to a unique identifier of the network request template, which may be represented with several characters. For example, identification information of a certain network request template is specifically BZ1001. A person having ordinary skill in the art should appreciate that there are many coding manners of the identification information of the network request template, which are not repeated herein one by one.

In the embodiment shown in FIG. 2, the solution of the present invention not only can reduce the time to transmit the network request to the server by the client terminal while ensuring proper transmission of network data, and improve the speed at which the client terminal accesses the network; but also can judge that a network request newly generated by the client terminal may be identical to the pre-stored network request template. If they are identical, the client terminal only needs to transmit to the server the identification information of the network request template, thus reducing the data amount transmitted to the server by the client terminal to a greater extent and reducing the time to transmit the network request to the server by the client terminal; in addition, the server does not need to make any calculation and restoration operations.

Embodiment 3

Referring to FIG. 3, FIG. 3 illustrates a further network data transmission method; the method is applied to a client terminal. The method provided in this embodiment can reduce the transmission amount of data transmitted to the server by the client terminal. The method includes:

Step S301. A network request is acquired.

The network request refers to a network request between a client terminal and a server, for example, an HTTP request header. A person having ordinary skill in the art should appreciate that may also be other requests. As each network request contains a great number of repeated data, the client terminal is transmitting to the server a significant amount of repeated data all the time.

Step S302. A network request template in a template group of which storage time exceeds preset time is deleted.

The template group includes multiple network request templates; as resources of the client terminal and the server are limited and data cannot be buffered without limit, a certain number of network request templates in the template group may be periodically deleted. The preset time is a time period that a user can set on his/her own.

Step S303. The data amount of discrepant data of the network request and each network request template in the template group is calculated.

The discrepant data is data that the client terminal has to transmit to the server; therefore, the less the discrepant data is, the less the data amount that the client terminal needs to transmit to the server is; accordingly, the data amount of discrepant data of the network request and each network request template in a template group is calculated, and a network request template of which the data amount is minimum is selected, so that the transmission amount of data transmitted to the server by the client terminal can be reduced.

Step S304. A network request template of which the data amount is minimum is selected in the template group.

Step S305. The network request is compared with a network request template pre-stored on a client terminal to obtain discrepant data and identical data.

The client terminal may store multiple network requests that have been transmitted before, and take the pre-stored network requests as a network request template. After the client terminal newly generates a network request, the network request is compared with a pre-stored network request template, so as to obtain discrepant data and identical data. The discrepant data refers to a part of the network request which is added relative to the network request template, and the identical data refers to a part of the network request which is identical to the network request template.

Step S306. Position information of the discrepant data and the identical data in the network request template is determined.

After the discrepant data and the identical data are obtained, position information of the discrepant data and the identical data in the network request template is determined. The functions of the position information are as follows: it is possible to find the identical data in the network request template by using the position information, it is also possible to determine by using the position information what position the discrepant data should be placed in the network request template, and thus the network request can be restored by using the position information, the discrepant data and the network request template.

During step S305 and step S306, it is feasible to use one algorithm for implementation. For example, discrepancy operation is performed on the network request and the network request template through a reversible binary diff algorithm, and the discrepant data and the position information can be obtained finally through the algorithm. A person having ordinary skill in the art should appreciate that it is also feasible to use other methods for implementation, for example, an open source xdelta algorithm, a google's vcdecoder algorithm, an open source diffutils algorithm and so on, all of which can achieve discrepancy operation on the network request and the network request template. Finally, the discrepant data and the position information calculated are taken as actually transmitted parts. Because the discrepant data does not have the same part between the network request and the network request template, the size of the discrepant data may be far less than that of the original network request.

Step S307. Identification information of the network request template, the discrepant data and the position information are transmitted to a server, where the identification information will be used to search for, by the server, the network request template pre-stored on the server and corresponding to the identification information, and the network request template, the discrepant data and the position information will be used to restore, by the server, the network request.

The identification information of the network request template, the discrepant data and the position information are transmitted to the server, in order that the server restores the network request by using the network request template, the discrepant data and the position information. The identification information of the network request template refers to a unique identifier of the network request template, which may be represented with several characters. For example, identification information of a certain network request template is specifically BZ1001. A person having ordinary skill in the art should appreciate that there are many coding manners of the identification information of the network request template, which are not repeated herein one by one.

In the embodiment shown in FIG. 3, the solution of the present invention not only can reduce the time to transmit the network request to the server by the client terminal while ensuring proper transmission of network data, and improve the speed at which the client terminal accesses the network; but also can reduce the transmission amount of data transmitted to the server by the client terminal.

Embodiment 4

Referring to FIG. 4, FIG. 4 illustrates a further network data transmission method. The method is applied to a client terminal. The method provided in this embodiment can retransmit a complete network request in the case that the transmitted data is lost, garbled and so on. The method includes:

Step S401. A network request is acquired.

The network request refers to a network request between a client terminal and a server, for example, an HTTP request header. A person having ordinary skill in the art should appreciate that the network request may also be other requests. As each network request contains a great number of repeated data, the client terminal is transmitting to the server a significant amount of repeated data all the time.

Step S402. The network request is compared with a network request template pre-stored on a client terminal to obtain discrepant data and identical data.

The client terminal may store multiple network requests that have been transmitted before, and take the pre-stored network requests as network request templates. After the client terminal newly generates a network request, the network request is compared with a pre-stored network request template, so as to obtain discrepant data and identical data. The discrepant data refers to a part of the network request which is added relative to the network request template, and the identical data refers to a part of the network request which is identical to the network request template.

Step S403. Position information of the discrepant data and the identical data in the network request template is determined.

After the discrepant data and the identical data are obtained, position information of the discrepant data and the identical data in the network request template is determined. The functions of the position information are as follows: it is possible to find the identical data in the network request template by using the position information, it is also possible to determine by using the position information what position the discrepant data should be placed in the network request template, and thus the network request can be restored by using the position information, the discrepant data and the network request template.

During step S402 and step S403, it is feasible to use one algorithm for implementation For example, discrepancy operation is performed on the network request and the network request template through a reversible binary diff algorithm, and the discrepant data and the position information can be obtained finally through the algorithm. A person having ordinary skill in the art should appreciate that it is also feasible to use other implementation methods, for example, an open source xdelta algorithm, a google's vcdecoder algorithm, an open source diffutils algorithm and so on, all of which can achieve discrepancy operation on the network request and the network request template. Finally, the discrepant data and the position information calculated are taken as actually transmitted parts. Because the discrepant data does not have the same part between the network request and the network request template, the size of the discrepant data may be far less than that of the original network request.

Step S404. Identification information of the network request template, the discrepant data and the position information are transmitted to a server, where the identification information will be used to search for, by the server, the network request template pre-stored on the server and corresponding to the identification information, and the network request template, the discrepant data and the position information will be used to restore, by the server, the network request.

The identification information of the network request template, the discrepant data and the position information are transmitted to the server, in order that the server restores the network request by using the network request template, the discrepant data and the position information. The identification information of the network request template refers to a unique identifier of the network request template, which may be represented with several characters, for example, identification information of a certain network request template is specifically BZ1001. A person having ordinary skill in the art should appreciate that there are many coding manners of the identification information of the network request template, which are not repeated herein one by one.

Step S405. Whether a retransmission instruction transmitted by the server is received is judged, and if yes, step S406 is performed.

In the process of transmitting data to the server by the client terminal, various possibilities may result in that the data transmitted to the server by the client terminal is lost, garbled and so on; therefore, in this case, the server may usually transmit to the client terminal a retransmission instruction, and once receiving the retransmission instruction transmitted by the server, the client terminal will transmit to the server a complete network request generated by the client terminal.

Step S406. The network request is transmitted to the server.

In the embodiment shown in FIG. 4, the solution of the present invention not only can reduce the time to transmit the network request to the server by the client terminal while ensuring proper transmission of network data, and improve the speed at which the client terminal accesses the network; but also can retransmit a complete network request in the case that the transmitted data is lost, garbled and so on.

Embodiment 5

Referring to FIG. 5, FIG. 5 illustrates a further network data transmission method. The method is applied to a server. The method provided in this embodiment can avoid wasting the data traffic of the client terminal and reduce the time to transmit the network request to the server by the client terminal, thus improving the speed at which the client terminal accesses the network, and the method includes:

Step S501. Identification information of a network request template, discrepant data and position information transmitted by a client terminal are received.

The discrepant data and identical data are obtained by the client terminal after comparing an acquired network request with the network request template stored therein, and the position information is determined by the client terminal according to positions of the discrepant data and the identical data in the network request template.

Step S502. The network request template corresponding to the identification information is searched.

The server may store multiple network requests that have been received before, and take the pre-stored network requests as a network request template. The server end pre-stores a corresponding relationship between network request templates and identification information, and each piece of identification information corresponds to a unique network request template; therefore, after the identification information is acquired, the corresponding network request template can be found with the identification information.

Step S503. The network request is restored according to the network request template, the discrepant data and the position information.

The network request is restored according to the network request template, the discrepant data and the position information through a reversible binary diff algorithm. A person having ordinary skill in the art should appreciate that the network request may also be restored with other methods, for example, an open source xdelta algorithm, a google's vcdecoder algorithm, an open source diffutils algorithm and so on. However, the algorithm used by the server has to be consistent with that used by the client terminal, so as to ensure that the server can perform reverse operation.

In the embodiment shown in FIG. 5, data transmitted to a server by a client terminal includes identification information of a network request template, discrepant data and position information. Because the data transmitted to the server by the client terminal does not include identical data of a network request and the network request template, a significant amount of repeated contents are reduced, thus reducing transmission of network data. Moreover, after receiving the data transmitted by the client terminal, the server can restore the network request by using the network request template, the discrepant data and the position information, thus ensuring correctness of the transmission of network data. Therefore, the solution according to the present invention reduces the time to transmit a network request to the server by the client terminal while ensuring proper transmission of network data, thus improving the speed at which the client terminal accesses the network.

Embodiment 6

Referring to FIG. 6, FIG. 6 illustrates a further network data transmission method. The method is applied to a server, according to the method provided in this embodiment, in the case that identification information merely containing a network request template is received, it is only needed to find a network request template corresponding to the identification information and take the network request template as a network request, thus greatly shortening the time to receive data transmitted by the client terminal to the server, and the method includes:

Step S601. Whether received data transmitted by a client terminal merely contains identification information of a network request template is judged, if yes, step S602 is performed, and otherwise, step S603 is performed.

If the received data transmitted by the client terminal merely contains the identification information of the network request template, it indicates that the client terminal has found a network request template identical to the network request, and thus the client terminal will only transmit the identification information of the network request template, and the server only needs to find a network request template corresponding to the identification information and take the network request template as a network request, thus greatly shortening the time to receive data transmitted by the client terminal to the server.

Step S602. A network request template corresponding to the identification information is determined, and the network request template is taken as a network request.

Step S603. Identification information of the network request template, discrepant data and position information transmitted by the client terminal are received.

The identification information of the network request template, the discrepant data and the position information are transmitted from the client terminal. The position information is determined by the client terminal according to position information of the discrepant data and identical data in the network request template, the discrepant data and the identical data are obtained by the client terminal by comparing the network request with the network request template, and the network request is generated by the client terminal.

Step S604. The network request template corresponding to the identification information is determined.

The server may store multiple network requests that have been received before, and take the pre-stored network requests as a network request template. The server end pre-stores a corresponding relationship between network request templates and identification information, and each piece of identification information corresponds to a unique network request template. Therefore, after the identification information is acquired, the corresponding network request template can be found through the identification information.

Step S605. The network request is restored according to the network request template, the discrepant data and the position information.

The network request is restored according to the network request template, the discrepant data and the position information through a reversible binary diff algorithm. A person having ordinary skill in the art should appreciate that the network request may also be restored with other methods, for example, an open source xdelta algorithm, a google's vcdecoder algorithm, an open source diffutils algorithm and so on. However, the algorithm used by the server has to be consistent with that used by the client terminal, so as to ensure that the server can perform reverse operation.

In the embodiment shown in FIG. 6, the solution provided in the present invention can reduce the time to transmit the network request to the server by the client terminal while ensuring proper transmission of network data, and improve the speed at which the client terminal accesses the network. Moreover, in the case that identification information only containing a network request template is received, it is only needed to find a network request template corresponding to the identification information and take the network request template as a network request, thus greatly shortening the time to receive data transmitted by the client terminal to the server. In addition, the server does not need to make any calculation and restoration operations.

Embodiment 7

Referring to FIG. 7, FIG. 7 illustrates a further network data transmission method. The method is applied to a server. According to the method provided in this embodiment, in the case that the server has not found a network request template corresponding to identification information, a client terminal is required to retransmit complete network data, to avoid that an error occurs again in a transmission process. The method includes:

Step S701. Identification information of a network request template, discrepant data and position information transmitted by a client terminal are received.

The discrepant data and the identical data are obtained by the client terminal by comparing an acquired network request with the network request template stored therein, and the position information is determined by the client terminal according to positions of the discrepant data and the identical data in the network request template.

Step S702. Whether a network request template corresponding to the identification information is found is judged, if yes, step S704 is performed, and otherwise, step S703 is performed.

There are several situations where the server does not find the network request template corresponding to the identification information, the first one is that the server has not yet stored the identification information and the network request template; the second one is that the identification information loses some data in the process of transmitting the identification information to the server by the client terminal, and so on. In some embodiments, no matter which situation it belongs to, a retransmission instruction may be transmitted to the client terminal.

Step S703. A retransmission instruction is transmitted to the client terminal.

The retransmission instruction refers to a generated complete network request that the client terminal is required to transmit, to avoid that an error occurs again in the transmission process.

Step S704. A network request template corresponding to the identification information is determined.

The server may store multiple network requests that have been received before, and take the pre-stored network requests as a network request template. The server end pre-stores a corresponding relationship between network request templates and identification information, and each piece of identification information corresponds to a unique network request template. Therefore, after the identification information is acquired, the corresponding network request template can be found through the identification information.

Step S705. A network request is restored according to the network request template, the discrepant data and the position information.

The network request is restored according to the network request template, the discrepant data and the position information through a reversible binary diff algorithm. A person having ordinary skill in the art should appreciate that the network request may also be restored with other methods, for example, an open source xdelta algorithm, a google's vcdecoder algorithm, an open source diffutils algorithm and so on. However, the algorithm used by the server has to be consistent with that used by the client terminal, so as to ensure that the server can perform reverse operation.

In the embodiment shown in FIG. 7, the solution provided in the present invention can reduce the time to transmit the network request to the server by the client terminal while ensuring proper transmission of network data, and improve the speed at which the client terminal accesses the network; moreover, in the case that the server has not found a network request template corresponding to the identification information, the client terminal is required to retransmit complete network data, to avoid that an error occurs again in the transmission process.

Step S801. Identification information of a network request template, discrepant data and position information transmitted by a client terminal are received.

The identification information of the network request template, the discrepant data and the position information are transmitted from the client terminal. The position information is determined by the client terminal according to position information of the discrepant data and identical data in the network request template, the discrepant data and the identical data are obtained by the client terminal by comparing the network request with the network request template, and the network request is generated by the client terminal.

Step S802. A network request template corresponding to the identification information is determined.

The server may store multiple network requests that have been received before, and take the pre-stored network requests as a network request template. The server end pre-stores a corresponding relationship between network request templates and identification information, and each piece of identification information corresponds to a unique network request template; therefore, after the identification information is acquired, the corresponding network request template can be found through the identification information.

Step S803. A network request is restored according to the network request template, the discrepant data and the position information.

The network request is restored according to the network request template, the discrepant data and the position information through a reversible binary diff algorithm. A person having ordinary skill in the art should appreciate that the network request may also be restored with other methods, for example, an open source xdelta algorithm, a google's vcdecoder algorithm, an open source diffutils algorithm and so on. However, the algorithm used by the server has to be consistent with that used by the client terminal, so as to ensure that the server can perform reverse operation.

Step S804. An authentication code transmitted by the client terminal is received, and the authentication code is obtained by the client terminal by using a preset algorithm to calculate data in the network request.

In order to authenticate whether data transmitted to the server by the client terminal is correct or not, the server may receive an authentication code obtained by the client terminal by using an MD5 algorithm or a hashkey algorithm to calculate data in the network request; after the server receives the authentication code, the server may calculate data of the restored network request by using the MD5 algorithm or the hashkey algorithm to obtain an information code, then the server compares whether the authentication code and the information code are the same or not, if they are the same, it indicates that the transmitted data is flawless, and if they are not the same, it indicates that the transmitted data is flawed and the client terminal is required to retransmit a complete network request.

Step S805. Data in the restored network request is calculated by using the preset algorithm to obtain an information code.

Step S806. Whether the authentication code is identical to the information code is judged, if yes, step S807 is performed, and otherwise, step S808 is performed.

Step S807. It is displayed that the restored network request is correct.

Step S808. A retransmission instruction is transmitted to the client terminal.

In the embodiment shown in FIG. 8, the solution provided in the present invention can reduce the time to transmit the network request to the server by the client terminal while ensuring proper transmission of network data, and improve the speed at which the client terminal accesses the network; moreover, it is feasible to authenticate whether data transmitted to the server by the client terminal is correct or not, and if no, it indicates that the transmitted data is flawed and the client terminal is required to retransmit a complete network request.
